Crunchy Wafer product
Mate of the Art
The pxesent invention relates to wafer-based confectionery
products which in general comprise two outer wafex layexs,
zo optionally one or more inner wafer layers and cream fillings
in between. Such wafer-based confectionexy produote are
widely known and well accepted consumer products.
The wafer layers axe made from commonly known batter
1s compositions which comprise for example wheat flour, salt,
vegetable oil, Lecithin, sodium bicarbonate and water. The
wafer layers must have a crunchy texture in order to achieve
consumer acceptance. The disadvantage of known wafer-based
confectionery products is that the cxunchy texture of the
2o wafer layers becomes doughy upon continued chewing.
Therefore, there is a demand for improved wafer-based
confectionery groducts.
zt is the object of the present invention to provide new
25 wafex-based confectionery products which have a crunchy
texture not only at the beginning of consumption, but maintain
their crunchy texture upon continued chewing.
Suuunarv of the ~avention
The object o~ the present invention is achieved by a
confectionery product comprising two outer wafer layers,
optionally one or more inner wafer layers and cream fillings
between the wafer layers, wherein the wafer layers are made
3s from a material which includes cocoa powder.

It was surprisingly found that the use of adcoa powder in the
batter recipe fox the wafer layers improves the crunchy
texture of the confectionery product such that the crunchy
texture is maintained even upon continued chewing compared
s with known wafer-based confectionery products which lose theix
crunchiness after being chewed only twice or three times
because the wafer layers become doughy.
Detailed Description of the Invention
The present invention is based on the discovery that wafer
layers which contain cocoa remain crunchy upon continued
chewing. They do not loge the crunchy texture after being
chewed twice or three times as is the case with the known
i5 wafer-based products which do riot contain cocoa within the
wafer layers.
The wafer-based confectionery products which are available on
the market axe relatively small in size compared with the form
zo and dimensions of a regular chocolate bar. It was found
within the present invention that the eating pleasure and the
product performance with respect to its crunchiness is greatly
improved if the dimensions of the wafer-based confectionery
product are increased. Therefore,~the products of the present
2s invention preferably have the form and dimensions of a regular
chocolate bar. Regular chocolate bars normally have the
following dimensions:
length: about 90 mm,
width: about 30 mm,
3u height: about 21 mm.
No such wafer-based confectionery product is available on the
market.
The products of the present invention preferably have six ar
s5 seven wafer layers and correspondingly five or six cream
filling layers. purthermore, the products of the invention
are preferably enrobed with chocolate.

Batter recipes for making wafer sheets are widely known in the
prior art. A common wafer batter comprises tar example wheat
flour, salt, vegetable oil, lecithin, sodium bicarbonate and
water. For example, the following batter recipe can be used
for making the wafer sheets according to the present inven-
tion:
water 54-58% by weight
wheat flour 36-39% by weight
to Salt 0.6-0.9% by weight
Vegetable oil 1.5-1.8% by weight
Lecithin 0.2-0.3% by weight
Sodium bicarbonate 0.05-0.07% by weight
Cocoa powder 1-10% by weight
as
The cocoa powder is preferably u9ed in amounts of 2-8% by
weight, especially 3-6% by weight.
The cocoa powder can be of any origin. Preferably Ivory Goast
zo cocoa powder is used.
In a first step for producing the wafer-based confectionery
products of the present invention, the ingredients of the
batter recipe are mixed together in any Convenient mixing
Zs device. The viscosity as measured in a Ford Cup like
viscosimeter should be about 39-42 sec (flow out time) at
18 to 20~C.
The obtained batter ie then used for baking wafer sheets in a
3o commonly used wafer baking equipment. The wafer sheets have
dimensions which are designed according to the requirements of
the end product. Because of the cocoa content, the weight of
the wafer sheets increases to some extent. BasEd on a wafer
area of 1,300 cm' and a wafer thickness of 3.0 mm, the weight
35 increases up to about 60 g compared with S4 g for correspon-
ding wafer sheets containing no cocoa powder. The moiautre

content of the wafer sheets should be about 0.8 to 1.2% by
weight.
The wafer sheets are then spread With cream and stacked on top
s of each other as per product format. This form ie called a
wafer book.
Any known or useful cream can be used for the cream fillings.
There is no limitation whatsoever except that the cream
1o viscosity must be such that the Cream Can be set at ambient
temperatures.
As the next step, the wafer book ie cooled to set the cream
before cutting.. A~tez~waxds, the wafer book is divided into a
iS prascribed number of pieces in a common cutting station,
Then, after cutting, the wafer pieces are enrobed with
chocolate and then cooled, for example, in a cooling tunnel,
to set the final. crystal structure of chocolate.
2o Finally, the product is packaged according to common standard
procedures i,n any suitable foil.
The following example is illustrative of the ~.nvention and is
not intended as limiting.
EXam,~m
As a fzrst step in the production of the new wafer-based
30, confectionery product,.wafer sheets were produced from the
following materials including dark cocoa powder:
CA 02438591 2003-08-27
Water 75.00 kg
Wheat flour 50.00 kg
Salt 1.00 kg
Vegetable oil 2.20 kg
s Lecithin 0,35 kg
Sodium bicarbonate 0.08 kg
Cocoa powder 5.00 kg
(10/12 alkanized)
Total batch 133.63 kg
io
To produce the batter, the ingredients were mixed in a
Hebenstreit mixer according to the following procedure:
Inq~ed-Tents Mixinr~ time
7.5
Water (~./2)
Sodium bicarbonate 15 sec.
Salt
zo Wheat flour
Cocoa powder 60 sec.
water t1/2)
Lecithin
2s Vegetable oil 60 see.
xhe viscosity of the batter was 39 sea.
Wafer sheets were baked from the obtained batter in a common
3o wafer baking equipment. Baking time was 1.8 minutes. The
weight of the wafer sheets increased to 61 ~ 2 g per 1,300 cm~
(from 54 g without cocoa powder). The moisture content was
0.9% by weight.
35 The wafer sheets were then spread with cream and stacked an
top of each other to produce the so-called wafer book, which
was cooled afterwards to set the cream before cutting. The
wafer book was then divided into the prescribed number of
pieces in the cutting station. The obtained wafer bars were
ao enrobed with chocolate and conveyed to a cooling tunnel to set
the final chocolate crystal structure.

The wafer products had the following form and dimensions:
6 layers of wafer sheet
layers of cream filling
s Milk chocolate coating
Length: 92 mm
Width: 30 mm
Height: 21 mm
1o When compared with commercially available wafer-based confec-
tionery products, the wafer products of the present invention
had an excellent crunchy texture and maintained the
crunchiness upon continued chewing. The commercially
available wafer-based confectionery products lost their
is original crunchiness upon chewing and became doughy.
